Solution

1. Preparation

Gather tools and parts needed for the replacement.
Disconnect the battery to prevent any electrical issues.
Allow the engine to cool before starting work.

2. Remove Engine Covers

Remove the upper timing belt cover:
- Unscrew bolts using a socket set.
- Gently pry off the cover to avoid damage.
Remove the lower timing belt cover:
- Unscrew and detach any fasteners securing the lower cover.

3. Remove Accessory Components

Remove the serpentine belt:
- Use a belt tensioner tool to relieve tension and slip the belt off the pulleys.
Disconnect and remove any components obstructing access to the timing belt (e.g., the alternator or power steering pump).

4. Set Engine to Top Dead Center (TDC)

Rotate the crankshaft using a socket and ratchet until the timing mark on the crankshaft aligns with the TDC mark on the engine block.
Ensure the camshaft timing marks are also aligned.

5. Remove the Timing Belt

Loosen the tensioner bolt and remove the tensioner.
Carefully slide the timing belt off the camshaft and crankshaft sprockets.
Inspect the tensioner and idler pulleys for wear; replace if necessary.

6. Install New Timing Belt

Place the new timing belt around the crankshaft and camshaft sprockets, ensuring alignment with the timing marks.
Reinstall the tensioner and adjust the tension according to manufacturer specifications.
Rotate the crankshaft two full turns by hand to ensure proper alignment and tension.

7. Reassemble Engine Components

Reinstall the accessory components and serpentine belt.
Reattach the timing covers, ensuring all bolts are torqued to specifications.
Reconnect the battery.
